FIELD

The present disclosure relates, in general, to telecommunication cables and physical transmission mediums, and more particularly to tools and techniques for the installation of telecommunication cables in relation to existing cables.

BACKGROUND

Copper wire cabling has historically been used as a transmission medium for telecommunications. Copper cables, such as twisted pair cabling, traditionally used in telecommunications offer limited data bandwidth, and are also limited by the distances over which signals need to be carried in modern telecommunications. As demand for bandwidth and transmission speed increases, the use of existing copper cables has been replaced by other transmission media, such as optical fiber.

Typically, telecommunication lines are buried. Thus, to install new cable or replace existing copper cable, cost and labor-intensive processes are used. This may involve excavation and trenching of roads, residential areas, and other areas where the cable will be buried.

Accordingly, tools and techniques for the underground installation of new cables are provided.

FIG. 1 is a schematic illustration of a system 100 for underground cable installation. According to various embodiments, the system 100 includes a cable 105 with an outer sheath 110 and core 115, a boring attachment 120, hose 125, and compressor 130. FIG. 1 also depicts a work pit 135, top surface 140, and ground material 145. It should be noted that the components of the system 100 are schematically illustrated in FIG. 1, and that a variety of hardware configurations are possible in accordance with various embodiments.

In various embodiments, the boring attachment 120 may be coupled to the exterior of the cable 105 around the outer sheath 110. The boring attachment 120 may be configured move in at least one direction along a longitudinal axis of the cable 105. The boring attachment 120 may further be coupled to a compressor 130 via hose 125. The cable 105 may be a buried cable, surrounded on either side by ground material 145. A work pit 135 may be created to allow access to at least part of the cable 105 from the top surface 140, to allow the boring attachment 120 to be coupled to the cable 105.

In various embodiments, cable 105 may include an outer sheath 110 and core 115. The cable 105 may include any type of cable, buried or otherwise, such as those used for electrical transmission and telecommunications. Types of cable may include, without limitation, copper cables, telephone cables, twisted pair cables, and optical fiber cables, among others. In some further embodiments, the cable 105 may further include a housing configured to carry one or more sub-cables. For example, housings may include, without limitation, ducts (e.g., inner ducts), and cable conduits.

The outer sheath 110 of the cable 105 may act to hold together (e.g., house) one or more wires, conductors, optical fibers, or other transmission lines of the core 115. The outer sheath 110 may further serve as a protective cover to physically protect the cable from damage and wear due to movement, vibration, weather, moisture, and the ground material 145 surrounding the cable 105. Ground material 145 may include soil, silt, dust, sand, clay, gravel, rock, and water. Accordingly, the outer sheath 110 may include, without limitation, tubes, sleeves, shielding, and jackets surrounding the one or more wires, conductors, optical fibers, or other transmission lines of the core 115.

The core 115 may include one or more types of transmission media located inside or otherwise housed by the outer sheath 110. In some embodiments, the core 115 may be a single conductor, wire, optical fiber, or other transmission line. For example, the core 115 may be a single copper conductor core. In other embodiments, the core 115 may include multiple conductors, wires, optical fibers, cables, and/or other transmission lines of the same type, such as, for example multiple copper wire twisted pair cables. Alternatively, the core 115 may include multiple transmission lines of different types. For example, the core 115 may include one or more copper wire twisted pair cables, and one or more copper wires for power delivery. Accordingly, the core 115 may include one or more transmission lines of one or more transmission media types. In various embodiments, the cable 105 and/or core 115 may further include, in addition to the transmission lines, any associated insulation, shielding, cladding, buffering, or other inner material located adjacent to the interior of the outer sheath 110.

Accordingly, the outer sheath 110 may be configured to provide protection to the core 115 against physical stresses and the environment around the cable 105. Suitable materials for the outer sheath 110 may include, without limitation, rubber, thermoplastics such as polyvinyl chloride (PVC), polyurethane (PU), acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polyethylene (PE), polypropylene (PP), and other plastics.

In various embodiments, the boring attachment 120 may be configured to displace the ground material 145 around the outer sheath 110. Displacement of the ground material 145 may include, without limitation, loosening, removing, or otherwise moving the ground material 145. For example, in some embodiments, the ground material 145 may be compacted (e.g., compacted soil). Thus, the boring attachment 120 may be configured to loosen the compacted ground material 145. In other embodiments, the boring attachment 120 may be configured to move the ground material 145 away from the outer sheath 110. In various embodiments, the boring attachment may be configured to accomplish through mechanical action or hydraulically. For example, mechanical action may include, without limitation, vibrating, rotating, pistoning, hammering, drilling, grinding, boring, moling, or a combination of such actions. Hydraulic action may include the introduction of water to wash away the surrounding ground material 145. In some embodiments, water or another fluid may be used in combination with the mechanical action of the boring attachment 120. Thus, the boring attachment 120 may be configured to move longitudinally along the outer sheath 110, displacing surrounding ground material 145 along the length of the cable 105. In various embodiments, the amount of ground material 145 displaced, or alternatively, the amount by which the ground material 145 is displaced, by the boring attachment 120 may be adjusted. In some embodiments, ground material 145 may be determined by, without limitation, the amplitude, speed, or frequency of the mechanical action of the attachment. For example, rotation rate, vibration speed, vibration intensity (e.g., amplitude), direction of vibration, may each be adjusted according to desired displacement characteristics.

In some embodiments, the boring attachment 120 may further be configured to create a channel around at least part of the cable 105, pushing the ground material 145 away from the outer sheath 110. The channel may include a volume that coextends with the outer sheath 110. The channel may be formed to create spacing between the outer sheath 110 and the ground material 145. In some embodiments, the channel may be formed such that separation between the outer sheath 110 and ground material 145 occurs over at least part of the outer sheath 110 circumferentially. In further embodiments, the channel may be formed over the entire circumference of the outer sheath 110, surrounding the outer sheath 110 on all sides.

Accordingly, in various embodiments, the ground material 145 may be displaced utilizing the boring attachment 120 and compressor 130. The boring attachment 120 may be coupled to the compressor 130 via the hose 125. The boring attachment 120 may be configured to be actuated by the compressor 130. In various embodiments, actuation may include, without limitation, pneumatic, hydraulic, or electrical actuation. When positioned over the outer sheath 110, the boring attachment 120 may be actuated to displace the ground material 145. In some embodiments, the boring attachment 120 may displace the ground material 145 by mechanical action, or alternatively, by hydraulic boring.

In some embodiments, the boring attachment 120 may further be configured to advance in one or more directions along the cable 105 while displacing the ground material 145. The boring attachment 120 may, in some examples, advance along the cable 105 through the action of displacing the ground material 145. For example, vibration, rotation, or the moling action of the boring attachment 120 may cause the boring attachment 120 to advance in one or more directions along the cable 105. In some embodiments, the boring attachment 120 may be advanced by mechanically feeding the hose 125 or retracting the hose 125.

In various embodiments, the boring attachment 120 may have a sleeve-like structure that may be fit over the outer sheath 110 of the cable 105. In other embodiments, the boring attachment 120 may have other structural configurations. For example, the structure of the boring attachment 120 may include, without limitation, a full or partial sleeve that is fit around the outer sheath 110, a collar, which may be opened and closed, that is secured around the outer sheath 110, or a probe-like device adjacent to the outer sheath 110 and attached to a guide, among other configurations. Moreover, in some embodiments, the boring attachment 120 may further include, without limitation, one or more of a pneumatic tool (e.g., piston vibrator), drill (e.g., toothed, twist, spade, unibit, step, hole, etc.), mole, impact tool, or other tooling suitable for displacing the ground material 145.

In further embodiments, the cable 105 or the boring attachment 120 may include a guide to accommodate movement longitudinally along the cable 105. In some embodiments, the guide may be separate from the cable 105 or boring attachment 120. In addition to moving longitudinally, the boring attachment 120 may further be configured to rotate around the outer sheath 110 circumferentially. Accordingly, the guide may include, without limitation, rails, tracks, bearings, loops, and sleeves. In some embodiments, the outer sheath 110 of the cable 105 may, itself, act as the guide for the boring attachment 120 to follow.

In various embodiments, once the ground material 145 has been displaced, a new cable may be installed. The new cable may include, without limitation, one or more new transmission lines, cables, or conduits (e.g., inner duct). Thus, in some embodiments, the boring attachment 120 may be configured to couple to the new cable, and move the new cable into position through the displaced ground material 145. In some embodiments, this may occur concurrently with the displacement of the ground material 145 by the boring attachment, while in other embodiments, the new cable may be placed by the boring attachment 120 after the ground material 145 has already been displaced. In yet further embodiments, once the ground material 145 has been displaced, the cable 105 may be removed from the ground altogether.

In various embodiments, the boring attachment 120 may be configured to place the new cable in a desired position. Placing the new cable in a desired position may include, without limitation, pulling, pushing, laying, or feeding the new cable into the desired position. For example, the boring attachment 120 may be configured to be coupled to the outer sheath 110 and to position one or more new cables on either side of the cable, coextending adjacently with the cable 105. It is to be understood that in other embodiments, the one or more new cables may be placed in different positions, such as, without limitation, above or below the cable 105. In yet further embodiments, the new cable may instead be an inner duct configured to encase the cable 105. Accordingly, in some embodiments, the boring attachment 120 may be configured to pull the inner ducting over the buried cable 105 such that the buried cable 205 is enclosed within inner ducting.

In some embodiments, the boring attachment 120 may include a connector to allow one or more new cables both to attach to, and detach from, the boring attachment 120. For example, after the new cable has been placed in the desired positioned, the boring attachment 120 may be configured to detach from one or more new cables. In some embodiments, the boring attachment 120 may include a connector configured to allow the hose 125 and/or one or more new cables to be removably attached to the boring attachment 120. In various embodiments, the connector of the boring attachment 120 may include, without limitation, clamps (e.g., cable clamps, hose clamps, etc.), fittings (e.g., barb fittings, etc.), fasteners (e.g., cable fasteners, wire ties, etc.), hooks, and other suitable mechanisms.

In various embodiments, the compressor 130 may be configured to actuate the boring attachment 120 via the hose 125. Thus, the boring attachment 120 may be air, gas, fluid, or electrically driven. The compressor 130 may include, without limitation, air or gas compressors, fluid pumps, or a combination of compressors and pumps. Accordingly, in various embodiments, the compressor 130 may be configured to compress and/or pump air, nitrogen, carbon dioxide, argon, steam, water (in liquid form), or a combination different types of fluids. In an alternative set of embodiments, the compressor 130 may be an electrical power supply.

In yet further embodiments, the system 100 may include a tracking device configured to track the location of the cable 105, boring attachment 120, new cables, or a combination of the cable 105, boring attachment 120, and new cables. In some embodiments, the boring attachment 120 may include the tracking device, while in other embodiments, the tracking device may be separate from the boring attachment. In some embodiments, the boring attachment 120 may be steerable, based at least in part, on the location of the cable 105, as determined by the tracking device. The tracking device may include various sensors, without limitation, ground penetrating radar, ultrasound, sonar, and other suitable devices for determining the location of a buried cable 105.

FIGS. 2-4 illustrate various views according to different configurations and modes of operations for the system 100. The various modes of operation of the system 100 are described with respect to the FIGS. 2-4.
